My mom was reinstated over a decade ago after I followed the advice of an elder and did pretty much the same thing as the August KM suggests (I was "reaching out" and so I was in major "suck up" mode) My mom hardly ever attended meetings after her reinstatement and later told me that the only reason she went back was because she was afraid to lose me as a son.
As professor indicates, what kind of motivation is that? It is nothing more than arm-twisting, and so many df'd people who do come back end up doing little or nothing jw-wise after that, because all they crave and need as normal humans is to have contact with their friends and family....that's why they return; seldom is love for "Jehovah" or the jw religion a motivating factor. Even from the jw standpoint, can't God, who reads hearts, see through all that anyway? What's the point then?
